Features

Description

The SL28EB742 is a high-performance clock generator for supporting

Intel Cedarview platforms. The SL28EB742 is rated to support extended

grade temperature. Utilizing an inexpensive 14.318 MHz crystal, it is

capable of supporting multiple frequencies from four PLLs. The CPU

clock can support a frequency range from 83.33 to 166 MHz by

configuration of two strap pins. With a combination of strap pins and an

I2C, the device allows maximum configurability.
